Hurricane Maria was located over the waters northwest of Puerto Rico
and moving slowly away tonight. Tropical storm force winds have
largely ended, though occasional gusts above tropical storm force
will be possible overnight, particularly at higher elevations.
Rainfall amounts have ranged between 15 and 25 inches with 40 inches
or greater in isolated spots. Catastrophic flash flooding continues
across much of Puerto Rico with some rivers and tributaries
exceeding record levels. Travel is strongly discouraged tonight as
rushing flood waters continue covering many roads. Some bridges and
roadways have likely completely washed away and it will be very
difficult to see this at night when driving.
* FLOODING RAIN:
Additional impacts from flooding rain are still a concern. Remain
well guarded against life threatening flood waters having further
impacts of devastating potential across Puerto Rico and extensive
potential in the U.S. Virgin Islands.
Little to no additional impacts are anticipated at this time across
Puerto Rico and the U.S. Virgin Islands.
Any remaining storm surge flooding will subside overnight across
coastal areas of Puerto Rico and the U.S. Virgin Islands.
Do not return to evacuated areas until it is safe. Listen for the
all-clear signal from local authorities.
* OTHER PREPAREDNESS INFORMATION:
If your home or shelter was damaged, be alert to the smell of natural
gas leaks and cautious around exposed electrical wiring, broken
glass, jagged metal and wood, and protruding nails and screws.
Those who rode out the storm away from their home or business are
likely anxious to return. However, allow some time for work crews to
make a clear path for emergency vehicles. Downed power lines and
trees may be blocking roads and flood waters may have washed out or
overspread sections of key travel routes. Traffic lights may also be
out of service.
When inspecting damage, use flashlights rather than candles or flamed
lighting. Be aware of sparks that can ignite leaking gas or other
If using a generator, avoid carbon monoxide poisoning by following
instructions by the manufacturer. Make sure that the generator is run
in a well ventilated space.
Problems with sewer backups can further contaminate standing flood
waters. Keep children away. Also, listen for boil water alerts
relative to communities whose tap water may have become non-potable.
Do not wade through flood waters. Dangerous wildlife, contaminants,
and active power lines are all potential threats.
As it pertains to this event...this will be the last local statement
issued by the National Weather Service in San Juan PR regarding the
effects of tropical cyclone hazards upon the area.
